Description

Technical Field

[0001] The utility model relates to the technical field of concrete sampling, in particular to a concrete sampling device. Background Art

[0002] Concrete is an indispensable building material in construction projects. Concrete is a mixture of cement, coarse aggregate (crushed stone or pebbles), fine aggregate (sand), admixtures and water. Concrete needs to be sampled before use to detect the uniformity of the mixed concrete. This requires multiple sampling at different locations and depths to ensure the accuracy of the experiment.

[0003] At present, some concrete sampling is still done manually using tools such as buckets to dig out part of the concrete for sampling. The sampling location each time is very single, and it is impossible to sample concrete at different depths. The single sample causes deviation in the test data. This method not only consumes a lot of manpower and material resources, increases the burden on the staff, but also has low sampling efficiency. Therefore, we propose a concrete sampling device to solve the above problems. Utility Model Content
